Solution Approach 1:

The landing system is divided into three distinct layers: GPS layer for coarse positioning, RF triangulation layer for intermediate positioning, and physical gripping wires layer for precise final positioning. Each layer handles a specific range and precision requirement, allowing the system to achieve both high operational efficiency and sub-centimeter landing accuracy by progressively refining position through multiple specialized subsystems.

Solution Approach 1:

The system performs self-positioning and self-landing through autonomous navigation using GPS, RF triangulation, and automated gripping wire engagement. The drone independently calculates its position, determines the optimal landing spot, and executes the landing sequence without human intervention, achieving both high accuracy and operational efficiency simultaneously.

Solution Approach 1:

The charging system enables autonomous battery replacement through automated mechanisms. The drone navigates to the charging station, the system automatically detects battery status, and mechanical arms or conveyors perform battery exchange without human intervention. This maintains charging reliability through standardized procedures while dramatically improving operational efficiency by eliminating the need for skilled operators.

Inventive Principle:
Principle #25Self-service

4Reliability

If skilled operators are present for charging, then charging reliability is improved, but operational efficiency deteriorates due to increased response time and costs

Engineering Contradiction:

Solution Approach 1:

The charging infrastructure includes automated battery detection, validation, and replacement systems that operate independently of human operators. Sensors verify battery compatibility and charge levels, while mechanical systems perform the physical exchange and secure connections. This automation maintains high charging reliability through consistent procedural execution while eliminating response time delays and operational costs associated with skilled personnel.

Inventive Principle:
Principle #25Self-service
